20050727: IDV - Error trying to plot local GRIB file 2-D and 3-D fields (Mac OS X 10.3.9)

Hi Dave,
Have you gotten this data file to work with version 1.2b2 before or do you suspect this is a Mac OS X issue?
The GRIB support is rather new and there may be some bugs in the beta 2 version that you are running. We plan to have a new release of the IDV within the next few weeks.
In the mean time, could you make the GRIB file in question available to us (e.g. via ftp) so we can make sure we can support it? 

Thanks,
Doug

I've just installed IDV v1.2b2 on a number of Mac G4 laptops running OS X 
10.3.9(with Java 3D installed.
As my first test of it, I' add a local data source consisting of a GRIB file 
(GFS model output) and
selected first a 2-D and then later a 3-D field, but in both cases when I "Create Display" I get a series of error messages such as the one above. 

I haven't done a thorough survey yet, but this problem has come up on several 
machines
that I've tried so far.

We just upgraded the RAM on these machines to 1GB (third party RAM).

OK, what info have I failed to include here? There must be something!
